To 11. whom fr may concern-.-

Be it known that I, ToLBERT G. PETERMAX, a citizen of the Lmted States, and aresident of Cumberland, in the county of Allegany E and State of Maryland, have invented a new and Improved RailwaySpike and Tie-Plate,

of which the following is a full, clear, and eX- act description.

This invention relates to lmprovements 1n spikes and tie plates for railway-rails, the 5 Ob ect being to provide a spike so constructed 1 as not only to firmly hold the rail, but effectually prevent the passing of water downthe 3 spike to the tie, thus preventing rotting of the wooden tie at this point and consequent 3 loosening of the spike.

Another object is to provide a tie plate of novel rams-traction and for use with a spike.

I will describe a railway spike and tieplate embodying my invention, and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference I indicate corresponding parts in all the figures.

Figure l is aperspective view of spikes and a tie-plate embodying my invention. Fig. 2

. edges are longitudinally inclined, which will to some extent prevent lateral movements of the members one relatively to the other. Each member of the tieplate is provided at its base portion with a spike-opening 14, and each member is also provided at the top with a hook-shaped flange 15 for engaging over particularly adapted 5 l the base ofthe rail, as indicated in-Fig. 1. The flange 15 of one member of the tie-plate extends across the other member-that is, each member is provided with a lateral ofl'set l 16, which engages against the upper side ,of the base portion of the other member, and this offset 16 is provided with a spike-opening 1 17, desi ned to register with the s ike-open- 1 ing 14 of the companion plate. T e spike 18 has its head 19 concaved at one side, as indicated at 20, to engage against the curved outer surface of the flange 15. At three sides the lower portion of the head is pro- 1 vided with downwardly-extended flanges 21, which are shar ened at the lower edge, so as f to engage slig tly in the metal of the tieplate, thus preventing any ossible entrance of Water that might reach t e Wooden tie. Having thus described my invention, 1 claim as new and desire to secure by Letters Patent'- 1. The combination with a tie-plate of a spike having downwardlyextended flanges at three sides of its hea 2. The combination with a tie-plate of a spike having downwardly extended flanges at three sides of the lowerportion of its head, said flanges being sharpened at the lower ed e.

1 The combination with a tie-plate of a spike having a head concaved at one side and downwardly-extended flanges at three of its other sides, the said flanges being sharpened at the lower edge.

4. A railway tie-plate comprising two longitudinally-separated members, each mem-* her having on its upper side, a flange for e'n-v gaging over the base of a rail.

In testimony whereof I have signed my name to. this specification in the presence of twosubscribing witnesses.
